Solar Battery Vent Caps >> Water Miser Battery Caps

Through a physical recombination process, Water Miser Battery Vent Caps capture liquid electrolyte before it escapes the battery cell. There are two separate and distinct processes that limit evaporation of the combined water and acid solution.

First, gaseous electrolyte is passed through a condensation chamber filled with a proprietary material derived from Polypropylene Co-polymer. The surface area of this material is designed to attract and condense the liquid electrolyte and then subsequently redirect it back into the cell by means of the electrolyte return probe.

Any residual liquid that passes beyond the condensation chamber is further limited by a micro-porus cindered filter disc. This filter acts as a back-up to capture any remaining gaseous liquids. This combined process results in a battery that maintains a more consistent electrolyte level over the life of your battery.

Water Miser Vent Caps will fit 98% of all batteries used in solar storage applications. Most batteries of this type produced in the United States and abroad utilize the industry standard 1/4 turn bayonet attachment (see photo). Bayonet style vent caps do not have "threads" but use two characteristic bayonet wings that lock the cap into the cell cover.

NOTE: 8D and 4D series batteries maintain a smaller diameter vent cell opening therefore the Water Miser will not fit these batteries.

If you are still unsure of whether Water Miser Vents will fit your batteries, please feel free to EMAIL or call us at 1 (419) 290-1103 and we will confirm compatibility with your specific make and model of battery.
